Hi I am integrating a PHP5 script to a Webservice

As usual the API docs are quite sparse, although I have an email with 2 "service references"

When I click on the "service reference" URLs I see an HTML page asking me to run "svcutil.exe" followed by another url e.g. svcutil.exe http://some-url/sdfg.svc?wsdl

The app will make a first call to their webservice to get an auth key
Then the second call will use that key with some actual payload XML data

I believe I need some more URLs from the third party
Anyone dealt with this kind of stuff before?
